Cargo Sealing-Package Apparatus

ABSTRACT

A cargo sealing-package apparatus comprises a larger plastic film coated with a layer of adhesive and an appropriate-thick paper base board, both larger than a cargo, and cushion elements with elasticity are adapted to protrusions extending from the cargo. The cargo is first placed flat onto the base board and, together, moved to a conveying platform of a preparation area (a cargo-feeding zone) to be transported into a working area (a vacuum-molding zone) and lifted upwards via an ascending/descending machine into a vacuum-heating area, bringing up air to inflate the plastic film undergoing pre-heating operation. Then, the air is drawn out to thermo-seal the plastic film around the shape of the cargo and adhere it in vacuum-binding onto the surface of the base board. Finally, the cargo accurately bound in a vacuum space is moved to a cargo-outlet area, achieving the benefits of anti-shock, humid-proof, dustproof, and anti-oxidized functions thereby.

BACKGROUND OF THE INVENTION

The present invention relates to a cargo sealing-package apparatus, comprising a plastic film coated with a layer of adhesive thereon and an appropriate-thick paper base board wherein the plastic film is thermo-sealed onto the external shape of a cargo and adhered flat onto the surface of the base board to provide a vacuum-binding package so that moisture and dust from outside can be blocked from getting therein and the cargo is accurately bound in a vacuum space, achieving the benefits of anti-shock, humid-proof, dustproof, and anti-oxidized functions thereby.

Conventionally, goods are packed in cardboard cases to which foam elements are also adapted so that the goods won't get damaged due to the bumping in the process of conveyance. And to avoid shaking the goods inside the cardboard cases, the foam elements must be put to the four corners and both top and bottom sides of the goods and designed according to the external shape of the goods so as to securely frame and hold the goods in place, which will increase the packing materials applied and the voluminous packing materials will take a lot of space in storage. In addition to boosting the cost thereof, the large amount of foam elements applied also overdoes the package and harms the environment as well. In storage, moisture and heat can easily accumulate inside the cardboards and cause the oxidization of goods stored therein. Furthermore, the sealed cardboards can easily have dust or spiders getting therein via gaps disposed thereon, which can make dirty the goods stored therein.

SUMMARY OF THE PRESENT INVENTION

It is, therefore, the primary purpose of the present invention to provide a cargo sealing-package apparatus, comprising a plastic film coated with a layer of adhesive thereon and an appropriate-thick paper base board wherein the plastic film is thermo-sealed onto the external shape of a cargo and adhered flat onto the surface of the base board in vacuum-bound attachment thereto so that moisture and dust from outside can be blocked from getting therein and the cargo can be securely protected from the damage of humidity or erosion by air, achieving the benefits of humid-proof, dustproof, and anti-oxidized functions thereby.

It is, therefore, the second purpose of the present invention to provide a cargo sealing-package apparatus wherein cushion elements are adapted for supporting, providing a buffer effect to prevent the plastic film from getting pierced through by protrusions sticking out from the cargo and to efficiently reduce the defective rate in the sealing-package thereof; besides, the cargo is accurately bound in a sheer vacuum space to avoid the damages caused by bump or shock in the process of conveyance, avoiding the overuse of the conventional cargo package above and saving the cost as well as space in package thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1 showing a flow chart of the sealing-package process of the present invention (accompanied by FIGS. 2, 3). The present invention relates to a cargo package-sealing apparatus, comprising a plastic film 10 coated with a layer of adhesive thereon and a paper base board 20 of an appropriate thickness wherein the plastic film 10, composed of EVA (a bottom layer) and LDPE (a top layer), is larger than the base board 20, and both the plastic film 10 and the base board 20 are larger than a cargo A. In addition, cushions element 30 each equipped with elasticity are respectively adapted to protrusions sticking out from the cargo A. The sealing-package process thereof includes steps as follows:

First, the cargo A is placed flat onto the base board 20, and the cushion elements 30 are respectively put to the protrusions sticking out from the cargo A for supporting to form a buffer effect. Then the cargo A and the base board 20 are moved to a conveying platform of a preparation area (a cargo-feeding zone) to be transported into a working area (a vacuum-molding zone). At the working area, the cargo A along with the base board 20 is lifted upwards via an ascending/descending machine into a vacuum-heating zone wherein the plastic film 10, undergoing pre-heating operation, will be inflated by air brought up via the ascending cargo A and the base board 20 thereof Then, the air is drawn out, permitting the plastic film to thermo-seal onto the external shape of the cargo A and completely wrap it up thereby. And the plastic film 10 bound around the shape of the cargo A is also allowed to adhere flat onto the surface of the base board 20 in vacuum-bound attachment thereto. Thus, the inner surface of the plastic film 10 affected by the vacuum suction will descend along the depressed areas of the cargo A and form an airtight conjoining portion 11 therewith to keep a sheer vacuum space B therein. Then, the extra plastic film 10 is cut along the outline of the base board 20 or bound thereto via adhesive tapes. Finally, the bound cargo A is conveyed to a cargo-outlet area, completing a cargo sealing-package apparatus that can block the intrusion of moisture and dust from outside. Via the design of the vacuum space B formed between the plastic film 10 and the base board 20, the plastic film 10 can avoid the danger of getting pierced through by the protrusions sticking out from the cargo A, and the defective rate in the sealing-package thereof can also be reduced in an effective way. In addition, the cargo A, protected from the pressing of the plastic film 10, can be accurately bound and held in place inside the vacuum space B to prevent damages caused by bump or shock in the process of conveyance, economically avoiding the overuse of the above-mentioned conventional cargo package and reducing the cost thereof. And, depending on the volume of the cargo A, the cargo A can be directly stacked up in a pile as shown in FIG. 4 to save the space occupied, achieving humid-proof, dustproof, and anti-oxidized functions thereby.
